Gas Furnaces and Carbon Monoxide: The Risks and How to Protect Your Family

February 06, 2017
Whenever your gas furnace is running, carbon monoxide is being created. However, there is no cause for worry. It is a natural by-product of the fuel-burning process. As long as your furnace is running properly, it is carefully deposited outside your home. Carbon monoxide is stored inside your furnace’s heat exchanger until it is safely forced through the flue vent to the outdoors. Carbon monoxide poisoning is a product of a malfunctioning gas furnace.

Inhaling too much carbon monoxide prevents the body from using oxygen and can harm the central nervous system and heart. While carbon monoxide poisoning can injure anyone exposed to the gas, it is more risky for people with existing lung or heart problems, pregnant woman, infants and children. Here are some tips to ease your mine mind and preserve a healthy, comfortable and safe home.

1. Invest in carbon monoxide detectors. Carbon monoxide is a colorless and odorless gas that can’t be detected by humans. Without a detector, it’s nearly impossible to perceive carbon monoxide is gathering in your home. You may not know until someone starts showing symptoms of poisoning. Put carbon monoxide detectors on every floor of your home, ideally near bedrooms, to be alerted to rising levels before anyone gets sick.
2. Be sure your gas furnace was installed properly. If your gas furnace wasn’t installed by pros, you should have it looked at. The experts at PWA Heating & Cooling Inc can make sure your blower motor is installed correctly and that there are no flaws in your ductwork design. Carbon monoxide can accrue if there are problems in those territories.
3. Schedule annual maintenance. Annual maintenance is the best way to prevent carbon monoxide leaks from your gas furnace. During a yearly tune-up, the experts will clean your system and check it for malfunctions or problems. It’s also a decent idea to have any other gas-, coal- or oil-burning appliances professionally monitored as well.
4. Keep your air filter clean. A stoppage of airflow caused by a spoiled filter can cause carbon monoxide to escape your system. Set a reminder on your phone or mark your calendar to routinely check your air filter and clean or change it per the manufacturer’s specifications.
5. Always count on professionals to fix your gas furnace and other fuel-burning appliances.
